I suppose if you're really not lying. There is one thing you could do. You could place a shoe on your head while sitting in front of the monitor showing the e-mail while writing your username on your chest (to verify it's really you). Then make a picture of it and post it on Facepunch.

Of course if you don't do this, it's proof that you are lying.

It's obvious that you are faking. Why else won't you conform to the standard internet verification method mentioned above?
